Canadian pieces are not really known to have junk in the glass but once in awhile you get one that does, and it usually is pretty impressive. Here is a light yellowy straw that has cascades of microbubbles in the glass and along with that comes the carbon lines too.VVNM piece that will display great in a lit cabinet or underlit. Photo is one of my earlier pics taken in water with incandescent light hence the off colour. Satisfaction guaranteed. $28 PP in USA.
